Diamond Core Drill Bit for Concrete – Premium Black – Large Diameter Wet Cut

Large-diameter plumbing contractors rely on this wet-cut diamond core bit when drilling through reinforced concrete for main line installations and commercial waste stacks. The black-coated segments deliver consistent cutting performance in structural concrete applications up to 18 inches thick. Wet cutting reduces dust and extends segment life during continuous operation on job sites requiring multiple large-bore penetrations. The brazed diamond matrix handles aggregate and rebar without segment loss when paired with appropriate core drilling rigs. Requires constant water flow for cooling and debris removal during operation. Built for mechanical contractors, plumbers, and HVAC installers drilling large-diameter openings in commercial and industrial concrete structures.
